xcode7

问题 I'm currently using Xcode version 7.2.1, and I'm getting weird values displayed for most values in the debugger. The weird thing is it's always the same value. Other than a few values, all variables are listed as containing the value "00:30:00". The best way to show this is to give you an example. I have tried restarting Xcode, clean and build, re-booting, and even re-installing Xcode, but I can't seem to escape this weird value. If I put in print statements, all the values show up correctly

问题 I have created a self signed certificate with openssl and sha 256 like the following: openssl req -x509 -nodes -sha256 -days 365 -newkey rsa:2048 -keyout server.key -out server.crt and I've installed it correctly in my AMPPS server by configuring httpd-ssl.conf file. If I try to perform, on a web browser: https://localhost I correctly see that connection uses TLS 1.2. When I run my app under iOS 9 simulator, I guess that error (9813) is raised because my certificate is self signed. Is there a

问题 I'm trying to get UI testing set up for my project - I encountered a crash with previous betas. (See this stack overflow question if you are interested) Anyway, I was quite thrilled to try it with Xcode 7 Beta 5. I created a simple Single Page app, added a text field and button, and ran it in Simulator. The simulator loads but the app doesn't get installed. I've tried it in different simulators, all iOS 9 - same behavior in all of them. Anyone else see this behavior? Am I missing something?

问题 I'm working on an Ios app and i need to replace all the backgrounds color of my xib view from one code color to another, something like "replace #000000 with #666666". Can i do this search with Xcode? I think that is impossible but maybe there's a way... EDIT This is what i can find in a xib opened as source code: <color key="backgroundColor" red="0.1764705882" green="0.1529411765" blue="0.1333333333" alpha="1" colorSpace="custom" customColorSpace="sRGB"/> But i can't search colors anyway 来源：

问题 Using the latest PhoneGap what is the best guidance someone could give as to adding the Bundle Version and Build Number overlaying a PhoneGap Splash screen. I see this on other apps but most likely those apps may not have been built with PhoneGap. From what I have read you could use a UIView controller to do this to the didFinishLaunchingWithOptions method. I am not an Objective C coder and native apps are new to me so any guidance as to where to start would be helpful. I am on El Capitan

问题 I have a tableViewCell that uses a checkmark in accessoryType of cell. I have a function that puts the contents of the cell into textField and similarly removes the text from the text field when it is unchecked. It seems to work fine but if I check a cell and want to check a cell thats not visible (IOW) I need to scroll the tableView, the cell that was checked (is now not visible) seems to uncheck itself (Only when I check a new visible cell). The multi select works with visible cells only.

问题 I have an app that in iPhone 6 I want it to be scaled proportionally and zoomed. Basically I want to imitate the Applied ZOOM from Settings. At the moment, when I run the app with the Zoom mode from Settings, everything works fine but when I run it without that Zoom from Settings, the views displayed are smaller. How can I fix it? 回答1: From Apple's What's New in iOS documentation: To let the system know that your app supports the iPhone 6 screen sizes, include a storyboard launch screen file

问题 While running my app on iPhone, I needed to view the database contents. So I selected Devices in Xcode and chose my device. Thereafter, I selected my app and clicked on the Settings button which shows 3 options: Show container, Download container and Remove container. On clicking the Download container option, I was asked where I want to store the container. After selecting the location, I am getting the following error: An error occured while attempting to download the container from
